We found the factors 405,775 . The biggest common factor number is the GCF number.
So the greatest common factor 405,775 is 5.
Lets's calculate LCM of 90,5706
2 | 90, 5706 |
3 | 45, 2853 |
3 | 15, 951 |
5, 317 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 317 = 28530
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/28530
Therefore, the GCF of Fractions 405/90,775/5706 is 5/28530
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 90,5706 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,5706) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(90,5706) x common factors =18 x 1 = 18
LCM(90,5706) = ( 90 × 5706 ) / 18
LCM(90,5706) = 513540 / 18
LCM(90,5706) = 28530
